LIFUP will be performed during two sessions (one occurring after deep sedation is stopped and the second one occurring just before discharge). The proposed experiment will involve behavioral (i.e., CRS-R) and paramedical (i.e., MRI/fMRI and EEG) measurements just before and after each of the two LIFUP sessions (i.e., 5 non-consecutive minutes of stimulation in each session) in a small sample of patients (up to 15) in order to evaluate the feasibility of a full scale clinical trial. Outcome measures (i.e., GOSE and CRS-R) will be administered at discharge, 6 months and one year after injury. The duration of participation in the study will be a year.
